POURING SPOUT FOR mm; BAGS Filed Aug. 2 s, 1957 INVENTOR. Haber-2'" OMorn son United States Patent POURING SPOUT FOR WATER BAGS Robert 0. Morrison, Portland, 0reg., assignor of onehalf to Fishels Awning & Supply Co., Portland, Oreg., a copartnership Application August 28, 1957, Serial No. 680,814 4 Claims. (Cl. 222-543) This invention pertains to pouring spouts, and relates particularly to a pouring spout adapted for attachment to the self-cooling type of canvas water bag.

It is a principal object of the present invention to provide a pouring spout which is adapted for attachment to canvas water bags during assembly of the latter.

Another important object of this invention is the pro vision of a pouring spout constructed to insure positive attachment to a water bag during manufacture of the latter.

Still another important object of this invention is to provide a pouring spout for canvas water bags, which pouring spout includes an attaching tab and a closure cap, all constructed as an integral unit, preferably of synthetic plastic by a one-stage molding operation.

A further important object of the present invention is to provide a pouring spout for canvas water bags, which pouring spout is of simplified construction for economical manufacture and which is capable of positive attachment to a water bag with speed and precision.

The foregoing and other objects and advantages of this invention will appear from the following detailed description, taken in connection with the accompanying drawing, in which:

Figure 1 is a fragmentary view in side elevation of a canvas water bag having attached thereto a pouring spout embodying the features of this invention;

Figure 2 is a plan view of the water bag and pouring spout assembly of Figure 1; and

Figure 3 is a sectional view taken along the line 33 in Figure 2, and showing details of construction of the pouring spout.

The pouring spout of this invention comprises a hollow tube which is open at its ends, and an outwardly projecting tab 12 secured to or otherwise formed integral with the tube and extending laterally therefrom. In the preferred embodiment, the tube and tab are formed as an integral unit from a synthetic thermoplastic material, by a single-stage molding operation.

The tube preferably is provided at its lower end with an outwardly projecting peripheral head 14, which functions to reinforce the lower end of the tube and also provides an edge to form a water seal with the canvas bag 16, as explained more fully hereinafter. An outwardly projecting peripheral flange 18 also preferably is provided on the tube adjacent the upper end thereof. This flange functions to reinforce the upper end of the tubing and also provides a sanitary edge for the upper end of the canvas bag.

The inner wall of the upper end of the tube may be flared upwardly, as indicated, to accommodate a tapered cork or other internal form of closure. It is preferred, however, to provide the cap type of closure 20 illustrated, wherein the peripheral Wall 22 of the cap is formed with an internal shoulder 24 adapted to snap over an external bed 26 formed on the upper end of the tube. An external peripheral flange 28 or thumb flap is provided on the cap as a thumbnail abutment for facilitating removal of the cap.

In addition, it is preferred that the cap be joined integrally to the tube, to facilitate use of the water bag and to prevent accidental loss of the cap. Accordingly, the cap is joined to the tube by means of the flexible strap 30. In the preferred manufacture from synthetic thermoplastic material, the closure and flexible strap are formed integrally with the tube, in the one-stage molding operation mentioned hereinbefore.

During manufacture of the water bag, and while the upper end of the bag is still open, the pouring spout is attached in the following manner: The upper end of the canvas bag is opened wide adjacent one corner, by pulling apart the side walls 32, 34 of the bag. The tube 10 is inserted between said side walls adjacent the con- I necting edge thereof, with the tab 12 extending toward the opposite side. The canvas side walls are drawn tightly about the tube, whereupon the canvas is caused to abut firmly against the major portion of the periphery of the lower bead 14, thereby forming a water seal therebetween. The tab and the adjacent side walls of the canvas bag then are secured firmly together, by any convenient means.

In the plastic construction of the pouring spout assembly described hereinbefore, the tab 12 is sufficiently thin to permit its attachment to the side walls of the canvas bag by such means as stitching with needle and thread. Alternatively, attachment of the tab to the side walls of the canvas bag may be achieved by means of conventional hollow rivet 36 illustrated in the drawings. This procedure involves placing the opposed halves of the rivet on opposite sides of the canvas bag and pressing them together with a rivet tool. As the rivet halves come together, they punch out sections of the canvas walls 32, 34, thereby forming openings therethrough. The plastic tab 12 also accommodates penetration of the rivet sections and simultaneous formation of an opening therethrough, as in the manner of the canvas walls. The rivet tool subsequently upsets the end of the inner rivet section to form a projecting peripheral flange 38 which locks the two rivet sections together.

With the tab secured firmly to the canvas walls, the pouring spout tube is anchored firmly to the canvas bag. The upper edge of the side walls of the canvas surrounding the tube abut against the underside of the peripheral flange 18, the latter thereby forming a sanitary edge which conceals the canvas in the pouring area.

From the foregoing it will be apparent that the present invention provides a pouring spout unit of economical manufacture, which is readily attached to a conventional canvas water bag with maximum facility during manufacture of the latter, and which provides an cflicient and attractive pouring spout and integral closure therefor.

It will be apparent to those skilled in the art that various changes in size, shape and other details of construction described hereinbefore may be made without departing from the scope and spirit of this invention. Accordingly, it is to be understood that the foregoing description is primarily illustrative of the invention and is not to be considered as limiting the scope thereof.

Having now described my invention and the manner in which the same may be used, what I claim as new and desire to secure by Letters Patent is:

1. For use with a water bag having side walls and a top end, a pouring spout therefor, comprising a hollow tube open at its ends, and a tab on the tube projecting from the external side thereof and disposed in a plane passing through the axis of the tube, the tab and tube being adapted to be positioned between the side walls of a water bag with the tab secured to said side walls.

2. For use with a water bag having side walls and a top end, a pouring spout therefor, comprising a hollow tube open at its ends, a tab on the tube projecting from the external side thereof and disposed in a plane passing through the axis of the tube, a reinforcing peripheral bead projecting outwardly on the lower end of the tube, a peripheral flange on the tube projecting outwardly therefrom adjacent the upper end thereof, a closure for the upper end of the tube, and flexible strap means interconnecting the tube and closure, the tube and tab being adapted to be positioned between the side walls of a water bag with the flange overlying the upper edges of said walls and with the major portion of the bead engaging said side walls and with the tab secured to said side walls.

3. In combination with a water bag having side walls and a top end, a pouring spout therefor, comprising a hollow tube open at its ends, a tab on the tube projecting from the external side thereof and disposed in a plane passing through the axis of the tube, the tube and tab being positioned between the side walls of the bag, and attaching means securing the side walls and interposed tab together.

4. In combination with a water bag having side walls and a top end, a pouring spout therefor, comprising a hollow tube open at its ends, a tab on the tube projecting from the external side thereof and disposed in a plane passing through the axis of the tube, a reinforcing peripheral bead projecting outwardly on the lower end of the tube, a peripheral flange on the tube projecting outwardly therefrom adjacent the upper end thereof, a closure for the upper end of the tube, flexible strap means interconnecting the tube and closure, the tube and tab being positioned between the side Walls of the bag with the flange overlaying the upper edges of said walls and with said walls engaging a major portion of the periphery of said bead and attaching means securing the side walls and interposed tab together.
